蓝牙鼠标无法连接

这是我在 bluetoothctl 中看到的内容：

[bluetooth]# pair 11:21:EC:00:00:02
Attempting to pair with 11:21:EC:00:00:02
Failed to pair: org.bluez.Error.AlreadyExists
[bluetooth]# trust 11:21:EC:00:00:02
Changing 11:21:EC:00:00:02 trust succeeded
[bluetooth]# connect 11:21:EC:00:00:02
Attempting to connect to 11:21:EC:00:00:02
[CHG] Device 11:21:EC:00:00:02 Connected: yes
Failed to connect: org.bluez.Error.Failed br-connection-create-socket
[CHG] Device 11:21:EC:00:00:02 Connected: no

鼠标昨天还可以用，今天却不能用了。

如果我多次关闭并打开鼠标（当 bluetoothctl 正在运行时），那么我会看到以下内容：

[CHG] Device 11:21:EC:00:00:02 Connected: yes
[CHG] Device 11:21:EC:00:00:02 Connected: no
[CHG] Device 11:21:EC:00:00:02 Connected: yes
[CHG] Device 11:21:EC:00:00:02 Connected: no
[CHG] Device 11:21:EC:00:00:02 Connected: yes
[CHG] Device 11:21:EC:00:00:02 Connected: no
[CHG] Device 11:21:EC:00:00:02 Connected: yes
[CHG] Device 11:21:EC:00:00:02 Connected: no
[bluetooth]#

因此，它首先连接，然后立即断开连接。

如果我尝试手动连接（通过从 bluetoothctl 输入“连接 MAC”），那么我会在 syslog 中看到以下内容：

Sep 26 10:15:53 vivobook-linux bluetoothd[7134]: profiles/input/device.c:ioctl_is_connected() Can't get HIDP connection info
Sep 26 10:15:59 vivobook-linux bluetoothd[7134]: profiles/input/device.c:control_connect_cb() connect to 11:21:EC:00:00:02: Host is down (112)

说是主机宕机了，但实际上并没有宕机。

如果我将鼠标置于配对模式也无济于事。

更新以下是 btmon 的输出：

最后我可以让它以这种方式工作

  • 删除 11:21:EC:00:00:02
  • 关掉鼠标
  • 再次打开鼠标，进入配对模式
  • 蓝牙扫描
  • 信任 11：21：EC：00：00：02
  • 对 11:21:EC:00:00:02
  • 连接 11:21:EC:00:00:02

我不知道为什么，但我不得不完全移除该设备并再次添加。但不起作用。
